I have been told to shut down support to SSLV3 - TLS 1.0 - TLS 1.1 to all encrypted communications towards external web services.
Now, I have an IPSec/CentOS gateway in front of my Data Center.How can I check which protocol it's using? And, how can I disable SSLv3 and TLS < 1.2 from the tunnels created between my gateway nad external networks? Or rather, how can I guarantee that IPSec is "safe" against SSLV3?
